DUNE will have to operate continually, for more than a decade, streaming data out of its LArTPC detectors
at a total rate of multiple tens of terabits per second. For reference, MicroBooNE [1]} and ProtoDUNE [2]}, the two largest currently operating LArTPCs, stream images continually at a data rate of greater than 260 and 490 gigabits per second, respectively. Unlike DUNE, these experiments do not have a rare event search physics scope. Data reduction for these detectors is therefore achieved through a combination of external trigger signals informing when to record a small subset of that data, and additional real-time compression, filtering and/or zero-suppression carried out in FPGA and/or CPU (see, e.g. [1]}, [4]}).
